What to Focus On
- A differential equation contains derivatives or differentials.
- It relates a function to its rate of change.
- Used in physics, biology, engineering, and economics to model changing systems.
- Order = highest derivative present.
- Degree = power of the highest derivative after simplification.
- Degree is only defined when the equation is polynomial in derivatives.
- Linear: all terms in y and its derivatives are degree one and not multiplied.
- Non-linear: contains powers, products, or non-linear functions of y or its derivatives.
Common Mistakes to Avoid
The degree of a differential equation is simply the highest power of the dependent variable or function.
All first-degree differential equations are linear.
When forming a differential equation, differentiate only once regardless of the number of constants.
